Reproducible particle counting using the light-obscuration technique is often troublesome because no absolute standard is available. Therefore, at the Laboratory of Dutch Pharmacists the "calibration-in-time" method was developed. This method enables checking of the amount of particles counted from a diluted latex suspension as a function of time. A(More)
In western countries, laparoscopic gastric banding is increasingly used in the surgical treatment of morbid obesity. This study aimed to investigate the feasibility, safety, morbidity, and costs of an outpatient procedure (OP) compared with an overnight stay (OS). In a 2-year period, 50 consecutive patients were randomized to an OP group or an OS group. In(More)
In order to verify whether the sterilization process of 60 min at 100°C for invert sugar 20% is sufficiently effective to attain the generally accepted probability of survival of maximum 1×10−6, we determined the bioburden and the bioburdens heat resistance for this product. We examined 98 bottles by the membrane filtration method and found 84 bottles with(More)
To investigate the effect of cardiac output and liver blood flow on propofol concentrations in critically ill patients in the intensive care unit. Five medical/surgical critically ill patients were enrolled in this preliminary study. Liver blood flow was measured using sorbitol. The cardiac output was measured by bolus thermodilution.

Uit deze voorstudie wordt geconcludeerd, dat met sc.i.i, een verbeterde regulatie van de diabetes mogelijk lijkt. In een vervolgstudie (PICKUP e.a. I979a) werd gekeken naar de invloed van sc.i.i, en de gebruikelijke toedieningswijze van insuline op het metabolisme, met name naar de concentratie van lactaat en pyruvaat (twee belangrijke intermediaire(More)
In order to calculate the minimum sterilization process conditions to obtain the generally accepted sterility level (less than 1·10−6 probability of microbial survival), we determined the bioburden and its heat resistance of 500 ml large-volume parenteral bottles over a period of 5 years. For the bioburden determination 1,832 bottles were examined by the(More)
Glass bottles with rubber closures are in most Dutch hospitals the recipients for large and small volume parenterals. During ‘in-process control’, attention can be paid to the various qualities of these materials. In seven Dutch hospital pharmacies we tested the amount of particles and micro-organisms in these recipients before and after washing procedures.(More)
